Hi Guys, I'm planning on re-roofing my carport. It’s at a mild pitch and it’s roughly 20’ X 20’. We’d like to collect water from it eventually (for the garden) and we think a metal roof might be a good way to help ensure the water is clean (or, cleaner than say with an asphalt roof). Can you suggest a relatively cheap and light material for this application, or give me some guidance as to where to start looking? Thanks, Ken Bouley

I would probably look for something with a Kynar / Hylar finish for durability and also fungus resistance. I am assuming this will not be used for drinking water. I do not think that any roofing manufacturer will support that idea.

Hi Todd, thanks. It won't be for drinking water, no, but I'm under the impression there's different standards for plants that will be eaten vs. general gardening. We do want to use the water for vegatables, etc. Any thoughts on that? I'll look into your recommendation, surely. I'd be glad to follow up with a specific reference if that's approriate. I'm in Marin County in California. Thanks again, Ken

I have never heard of different standards for watering vegetables, etc. I would birng it up with the manufacturer of the roofing to make sure they're okay with it though.
